"CAVITATION" Special PressureCorr relaxation!!!
Hi; I want to model cloud cavitation arround a simple hydrofoil with Fluent. I work with version 6.1.22 of this software recently. In its documentation there is some guidlines suggested to obtain a converged solution. I begin the solution with a noncavitating condition and approach slowly to the operating condition. At a noncavitating condition, when I solve only the flow equations, I obtain a stable converged solution; But in the same condition(noncavitating i.e. a low velocity or a high pressure) when I add volume fraction equation of cavitation to equations, I do not have a converged stable solution.(the main problem is the "continuity" residue.) Of course this is by defult setting of "pressure limit" or"Termination criteria" or ... Because fluent documentation suggestion, when I type: (rpsetvar,'pressurecorrection/relax value) I recieved error: "invalid command[rpsetvar]" Can I set this relaxation in solution pannel? Where I should type this correctly? Thanks.

Re: "CAVITATION" Special PressureCorr relaxation!
(rpsetvar,'pressurecorrection/relax value)
That's a mistake: the "," behind "rpsetvar" has to be omitted. Try (rpsetvar 'pressurecorrection/relax 0.4) That should work.
